CHARLES H. KELLERMAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHALLENGE MACHINERY COMPANY, OF GRAND HAVEN, MICHIGAN,

A CORPORATION OF ILLINOIS.

PRINTERS GALLEY.

Application filed December 1 To all whowt it may concern:

Be it known that I, CHARLES H. KELLER- MAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printers Galleys; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in printers galleys; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

A printers galley made in accordance with my invention comprises the usual flat bottom plate and side walls and one end wall attached to the margins of the bottom plate to constitute the three-sided inclosure of the galley. The said Walls are formed of bars of rectangular cross-section and are attached to the bottom plate by rivets. The wall-bars are provided in their exterior lateral faces with longitudinal grooves, and the bottom plate and the lower portions of the wall-bars between said plate and grooves are provided with registering holes to receive the attaching rivets. The said rivets areupset or riveted at their lower and upper ends against the lower face of the bottom plate and the lower walls of the grooves of the bars, respectively, the rivets being thus made of less length than the vertical height of the bars. Anvil bars or strips of a cross-section corresponding to said grooves are inserted in the grooves in contact with the ends of the rivets, which extend into said grooves during the riveting operation, the upper ends of the rivets being upset against said anvil-bars by riveting pressure or blows applied to the lower ends of the rivets.

In making a printers galley embodying my invention I proceed generally as follows: The bars which constitute the walls of the galley are longitudinally grooved from end to end on their exterior lateral faces. T hereafter registering rivet-holes are formed in the bottom plate and the lower parts of the bars between the grooves and the bottom plate.

Anvil bars or strips are then inserted into Specification of Letters Patent.

I said grooves, rivets are inserted through 1 the registering holes of the bottom plate and bars with their inner or upper ends in contact with the anvil-bars, and finally the ends of the rivets are upset by riveting blows 0r pressure against the lower or outer ends of the rivets. After the rivets have been set into 1 place preparatory to upsetting them the assembled bottom plate and bars are inverted and placed upon a suitable solid support to properly support the same during the riveting operation. i In the drawings, Figure 1 is a perspective view of a printers galley made in accordance with my invention, showing one of the rivet ing-anvils inserted partially into the groove of one of the flange or wall-bars. Fig. 2 is a perspective view of one of the side wall-bars removed. Fig. 3 is a perspective view of one end of the bottom plate. Fig. 4 is a perspective view of one of the riveting anvil-bars. Fig. 5 is a fragmentary section taken through the bottom plate and one of the walls of the galley, illustrating an upset rivet and the riveting-anvil in the position it occupies during the riveting operation.

As shown in said drawings, 6 designates the bottom plate, 7 7 the side walls, and 8 the end wall, of a printers galley. The side and end walls are made of bars of rectangular crosssection and are attached to the upper faces of the bottom plate 6 at the side and end margins thereof by means of rivets 9. The said bars are provided on their exterior lateral faces with longitudinal grooves 10 and 11, respectively. The portions 12 and 13 of the bars between the grooves and bottom plate are provided with rivet-holes 14, through which and registering holes 16 of the bottom plate 6 the rivets 9 extend, the I said holes in the bars opening into the bot \toms of the grooves. The said anvil-bars are inserted in the grooves before the rivets are inserted through the registering holes of I the bottom plates and bars, the anvil-bars thus acting as stops to limit the insertion of the rivets. The original length of the rivets l is somewhat greater than the thickness of the bottom plate and the parts 12 and 13 of the wall-bars, so that when the rivets are in serted into place with their upper or inner ends in contact with the anvil-bar and before they are upset they extend at their lower ends somewhat beyond the lower face of the bottom plate 6. The rivets may be made of a material slightly harder than the material constituting the wall-bars, so that the spreading of the inner ends of the rivets as they are upset acts to spread outwardly the metal of the bars, and thereby produce a countersunk effect which serves to interlock the rivets with the bars. After the anvil-bar has been inserted in place and the rivets set in the rivet-holes the assembled parts are then in verted upon a suitable support, and the rivets are upset by the application of riveting blows or pressure against the ends of the rivets which project beyond the bottom plate. During such riveting operation the rivets are upset not only on their outer ends, but are upset at their inner ends against the anvil-bars. The anvil-bar for the end wall will be made of a length to fit in the groove 11 of the end wall 8. It will be observed that the upsetting of the rivets against the anvil-bars 7 has no tendency to mar or distort the Wall-bars, inasmuch as said anvilbar closely fits the grooves of. said wall-bars and supports the same.

It has been a common practice heretofore in the construction of printers galleys in attaching the wall-bars to the bottom plate to drill the rivet-holes through the entire depth of the wall-bars and to provide rivets of a length to reach through the bottom plate and wall-bars. A great disadvantage of this practice is that much annoyance is experienced in breaking the relatively small drills used in forming the holes through the entire depth of the wall-bars. Moreover, the time required to drill the rivet-holes through said bars is much greater than to drill the shorter holes through the lower portions 12 and 13 of the bars providedwith the grooves herein shown. By reason of the construction herein shown the attaching-rivets may be made of considerably less length, thereby efiecting a material saving. Furthermore, the attaching of the Wall-bars to the bottom plate by rivets which extend the time required- I entirely through the wall-bars makes it necessary to provide a riveting-anvil having a true and hard riveting-face of the size of the finished galley. In the .present instance, however, the riveting-bars 17 receive the force of the riveting blows, and it is only necessary to provide an ordinary support for the assembled parts during the riveting operation.

I claim as my invention 1. The improved printers galley described comprising a bottom plate and vertical walls, said walls consisting of bars provided in their exterior lateral faces with longitudinal grooves, formed nearer the upper than the lower margins of the walls, whereby the lower flanges formed by said grooves are deeper than the upper flanges, said bottom plate and the bars being provided with registering rivet-holes which extend through said lower deeper flanges and open into said grooves, and rivets in said holes which are upset at their inner and outer ends against the bottoms of said grooves and the bottom plate, respectively. E l

2. The improved printers galley described comprising a bottom plate and vertical walls, said walls consisting of solid bars which are cut on their exterior lateral faces to provide longitudinal grooves, located closer to the upper margins than the lower margins of said bars, said bottom plate and the bars being provided with registering rivet-holes which open into the bottoms of said grooves, and rivets in said holes which are upset at their inner and outer ends against the bottoms of said grooves and the bottom plate, respectively.

In testimony that I claim the foregoing as my invention I affix my signature, in presence of two witnesses, this 7th day of December, A. D. 1905.
